Application filed August 26, 1914. Serial No. 858,721.

To all whom it may concern:

Be it known that I, RICHARD K. Roaon, a citizen of the Llnited States,residing at Willard, in the county of Seneca and State of New York, raveinvented new and useful Improvements in Jombined Spirit-Levels andPlumb-Bobs; oi": which the following is a specification.

This invention relates to a combined spirit level and plumb hob, and ithas for its object to produce a simple device of this class which may beconveniently used in either capacity.

' A further object of the invention is to produce a combined plumb boband spirit level having a simple and improved attaching devicewhereby'it'may be quickly and conveniently connected with or detachedfrom a suspending cord.

' Viith these and other ends'in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointedout inthe claims.

In the accompanying drawing has been illustrated a simple and preferredform of I the invention, it being however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may beresorted to when desired.

In the drawing,-Figure 1 is a perspective view, showing the device inuse as a plumb showing is a transverse sectional view taken on the line3-3 in Fig. 2. Fig. d is a longitudinal sectiorial view taken on theline 4 -4 in Fig. 3.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved plumb bob comprises a casing 15 which is preferablyrectangular in cross section, although no limitation is made in thisrespect. The casing has a detachable lid 16 which may be held in position by fastening means, such as screws 17.

The two sides of the casing are provided with sight openings 18, and thelid 16, likewise, has a sight opening 19. A conical hook 22 and intowhich the looped end of acord 23 may be quickly adjusted and where saidcord will be quickly and accurately centered by the action of theconvergent side members of the V-shaped hook the apex of whichlies inthe longitudinal axis of the device.

A spirit level 25 is mounted in the casing 15 where it may be secured bya filling 26 of plaster of Paris or other suitable material ofa plasticnature which will enable the level to be held securely withoutobstructing the sight openings.

The operation and advantages of this invention will be readilyunderstood from the foregoing description, taken in connection with the.drawing.

Whcnf the device is to be used as a plumb bob, it is connected with thesuspending cord 23.. For use as a level it may be quickly detached fromthe cord and used in the well known manner of an ordinary spirit level.I

Having thus described the invention, what is claimed as new, is

1. A. device of the class described com prising a casing, substantiallysquare in cross section and including a bottom memher, an endmember,side members and a" lid, said side members and lid being provided withsight openings, a conical indicator fitted in the open end of thecasing, fastening members connecting the lid with the end member andwith the conical indicator, and a spirit level inset in the casing andvisible through the sight openings.

2. A. device of the class described comprising a casing, substantiallysquare in cross section and including a bottom memher, an end member,side members and, a lid, said side members and lid being provided withsight openings, a conical inclicator fitted in the open end of thecasing, fastening members connecting the lid with the end member andwith the conical indicator, and a spirit level inset in the casing andvisible through the sight openings; and In testimony whereof I aflix mysignature an attaching member consisting ofdahshank in presence of'twowitnesses. threaded into the end mem er an aving A a V-shaped hook, theapex of' which lies RICHARD ROACH' in the longitudinal axis of thedevice Witnesses:

whereby a looped cord connected therewith MARGARET W. RI H,

will be automatically centered. ISABELLA RoAcH.
